v2.9.0 adds new features, refactors tests, and improves docs. New features improve interoperability/transcoding between CBOR & JSON.

v2.9.0 passed fuzz tests and is production quality. However, the new TextUnmarshaler feature will continue being fuzz tested a bit longer due to recent changes. The recent changes are limited and don't affect other parts of the codec that passed ~2 billion execs fuzzing.
